Simple, clear and appealing presentation, just as it should be. Realistic testing example, applied on the real world github project was the most impressive part of this presentation.
Really enjoyed this talk yesterday.

Excellent clarification of core DDD concepts and definitions. Very profound explanation of all the significant building blocks of a domain-driven design.
Comprehensive lesson on DDD, suitable for intermediate and advanced developers.

I already knew much about the matter of this presentation which I encounter and apply on a everyday work, but I still really enjoyed Rob's talk and the manner in which he explains stuff.
Speaker provided a very clean clarification of a DI concept. Nice overview and comparison of various DI container solutions. I find this presentation very useful for novice developers and beginners.

This talk was a very good follow-up for a previously held workshop which I attended and it was a nice sequel in my opinion. I liked the step-by-step practical example of how DDD concepts/building blocks can be applied in case of developing information systems for schools.
I guess that this talk was undetermined for all the folks who weren't at the workshop.

I haven't worked with Sylius earlier, but this talk provided many useful insights about it, of which some were too detailed in my opinion for this type of presentation. I really liked the idea behind Sylius which is a modular, flexible, customizable system with decoupled components.

I follow Marco's blog, open-source contributions, social networks activity and I agree with and support most of his attitudes and views of things. That is why I already knew much of concepts and things that were presented here, but I never had a chance to hear in the form of a nicely thought talk.
I really liked points and advices on optional dependencies, logic switch parameters, mixed params/return values, value objects.
Marco is obviously a great presenter and he really nailed it with this talk which IMHO was the best one on this conference. This is how a conference talk should look like.

Attractive topic, very intriguing and interesting talk. But I'm under the impression that some machine learning basics were left out, so it was pretty hard for people new to the matter to follow this talk.

Amazing idea for improving performance of tests run. Very useful, practical, easy to follow presentation. Still there is plenty of room for improving/expanding talk's content, and author is aware of that.

Very motivating talk with plenty of good advice based on speaker's professional career. Particularly useful for people that are entering into IT industry. I really liked and agree with 9 to 5 person opinion.
Complain that I have is too rapid speech for my personal taste.

Nicely rounded story about middleware, from beginning to the end. Practically all the essential parts were mentioned, including upcoming PSR-15 standard.
Suggestions for improvements:
- describe middleware action handlers vs MVC controller actions
- talk in a more slower pace

Truly practical content covering essential ES and CQRS concepts, suitable for intermediate and advanced audience. Confident and comfortable speaker.
Improvement ideas:
- give more attention to very basics and fundamentals of the ES concept, perhaps some related DDD basics, too, and how it overpowers actual, widely used principles
- more examples of tools and frameworks that facilitate the idea or at least suggested solution for reusing staff that is necessary for ES, because we saw that "event-sourced" entities have lots of code in common

Instructive and valuable tips for first-time attendees, refreshing and enjoyable talk for experienced attendees. Fully in line with the spirit of the keynote talk. Well balanced mixture of speech and appealing images throughout.

Clear, comprehensive explanation of different principles and patterns that relate to IoC containers. Useful examples throughout the talk. Confident and well-prepared speaker.
Tips for slight improvements: shed more light on the very concept of Service Location (anti)pattern and side effects (coupling to the container) it produces if it leaks into the 'core', domain code.

Hi Arnout, thanks for the positive feedback! I definitely did not estimate the time well, probably rushed through few slides. I even removed a closing slide (longer talk) discussing Defensive Programming just a day before the talk, worried that I will exceed the time limit. Anyway, SPL base classes seems like a pretty good idea for enriching content, I'll definitely consider it.

This talk is an eye-opener for everyone who have a basic knowledge of the subject of replication. Speaker had a really good performance on the stage and was able to deliver advanced concepts in a clear and understandable way.

A well-conceived talk with a content that is an ideal balance of theory and very useful and relevant practical examples that explains Domain-driven design essence in a clear way. Speaker confident on the stage and managed to keep the attention of the audience throughout the talk in a convincing and amusing way.
